This is a handle (SHG) for a square Pyrex ceramic dish made of super heat-resistant glass, Pyrex Ceram. Please refer to the contents of the box for compatible sizes. This item was found while organizing my house. I believe it is quite old. Since there is a sponge inserted at the end of the handle, it is likely unused, but the box is deteriorated, and the handle itself feels somewhat old. I have another one of the same item. This item has been stored at home for a long time. Please check the images and understand the condition before purchasing.
